Clinical and Diagnostic Findings in Patients with Chromaffin Tumors: Pheochromocytomas, Pheochromoblastomas

摘要: Chromaffin tumors are defined as neoplasias composed of catecholamine-producing, -storing, and -secreting cells. They therefore develop not only in the adrenal medulla but also sympathetic paraganglia. Regardless their intra- or extra-adrenal localization, we shall use term pheochromocytoma for all expansive growing forms these pheochromoblastoma infiltrating metastasizing (Table 1; Kaser 1985). However, it must be emphasized that even nonmalignant considered lifethreatening disease. In fact, its endocrine activity may lead to death if tumor remains unrecognized untreated. correctly diagnosed, this neural crest can removed by surgery, most patients thus cured.
